When a capillary is dipped in water,water rises to a height $h$. If the length of the capillary is made less than $h$,then

$A$ capillary tube made of glass is dipped into mercury. Then

Why does the mercury level fall in a capillary tube? Explain.

Water rises to a height of $20 \ mm$ in a capillary tube. If the radius of the capillary tube is made $\frac{1}{3}rd$ of its previous value,what is the new height of the capillary rise (in $mm$)?

Three liquids have the same surface tension and have densities $\rho_1, \rho_2$, and $\rho_3$ $(\rho_1 > \rho_2 > \rho_3)$. In three identical capillaries, the rise of liquid is the same. The corresponding angles of contact $\theta_1, \theta_2$, and $\theta_3$ are related as:

$A$ capillary tube of radius $r$ is immersed in water and water rises in it to a height $h$. The mass of the water in the capillary tube is $m$. Another capillary of radius $2r$ is immersed in water. The mass of water that will rise in this tube is
